Berman says the channel debate rotates, the list does not
A pitch for flat-rate data runs into a second argument about what a credit cap does to the word unlimited.
Alex Berman argues that the cold email versus cold calling versus LinkedIn DMs fight settles nothing because all three channels run the same four-step lifecycle. A channel opens because reply rates beat the alternative, operators pile in, reply rates compress, the feed calls it dead, and volume rotates to the next channel. His conclusion is that whichever channel is winning this quarter is simply the one fewest people have crowded into yet.
The part he says does not rotate is the list. The addressable set you can pull by title, seniority, industry, company size and country is the same set cold email worked yesterday and cold calling works today.
The pitch underneath the argument
Berman is selling a conclusion that leads somewhere. He says he runs his lists through ScraperCity, which he describes as 419M+ B2B contacts at a flat $149 a month with unlimited pulls and no credit meter, queried from Claude Code over an MCP server so the agent assembles the file while you write first lines. He also says physical mail is next, and asks to be held to it.
That is an operator's framing of his own stack, not a test result. There are no reply rates, no send volumes and no comparison against another data vendor in the post. Treat the 419M figure as a vendor count until someone runs the same ICP query across two sources and publishes the match rates.
Unlimited, with an asterisk
Separately, Michel Lieben told Ahmed that their proprietary database is unlimited, and that for data you cannot find in there you can tap into external databases via credits. Ahmed's reply was one line, that it is not really unlimited if it is still capped by credits.
That exchange is small and it is the useful one. Flat-rate data pricing in this category tends to be flat on the vendor's own index and metered the moment the query reaches outside it. Which bucket your ICP falls into decides whether the flat fee is the real price.
For people sending, both of these are arguments in favour of buying data access, so the question to answer before you rebuild a list is which records sit in the proprietary index and which trigger an external lookup. Berman's lifecycle point stands on its own either way, and it is a reasonable reason not to rebuild your whole motion around whichever channel the feed is praising this month. It is not evidence that any particular database covers your segment.
The channel on top in any given quarter is just the one fewest operators have crowded into yet
not really unlimited if still capped by credits.
